CFM-powered 737s and 767-300s for me.
There's a lot of MD-80s around but I never get tired of them; they're nice looking aircraft, and once those are gone all we'll have left will be mostly twin engine 737-style jobs.
One interesting thing with everyone's post is how in everyone's location a particular type seems to prevail. For example, someone is sick and tired of Fokker 28's, when over here I never get to see any!
Perhaps we oughta do some trading eh?
IMissPiedmont, I agree with you on the comment about Boeing
I'd perhaps add the 747-200 to the lot as well.
